ABSTRACT

The invention relates to cosmetic and/or dermatological formulations containing lecithin and essential fatty acids, which ensure a maximal skin moisture supply to the skin with a simultaneous acceleration of metabolism processes, so that the healing process of damaged skin is supported.

The invention relates to cosmetic and/or dermatological formulations containing lecithin and essential fatty acids, which ensure a maximal skin moisture supply to the skin with a simultaneous acceleration of metabolism processes, so that the healing process of damaged skin is supported. Moreover, the formulations according to invention mediate a remarkably pleasant skin feeling.

The object of the present invention is to provide cosmetic and/or dermatological formulations, which ensure a maximal skin moisture supply to the skin and accelerate the healing process of damaged skin by the acceleration of metabolism processes.

This object is solved by the technical teaching of independent claim 1. Further advantageous designs, aspects and details of the invention result from the dependent claims, the description and the examples.

Surprisingly it was found, that a cosmetic and/or dermatological formulation solves the given object, if this formulation contains: lecithin; a native oil as lipid phase with a defined preferably high content of fatty acids, especially essential fatty acids, such as sunflower oil; as well as glycerin (and/or ethylene glycol, 1,3-propanediol and/or tert-butylalcohol); propylene glycol (and/or polyethylene glycol); benzyl alcohol (and/or benzyl acetone and/or benzaldehyde); phenylethyl alcohol (and/or 2-phenylacetate); benzyl alcohol (and/or phenylethyl alcohol) and purified water.

Lecithin belongs to the phosphoglycerides group, which are also referred to as phosphatides or phospholipids. These compounds are fat-like triglycerides with two long-chain fatty acids and one phosphoric acid moiety, at which an ammonium moiety is bound as shown:

Lecithin is not a pure substance but a mixture of different fatty acid esters depending on its origin. Especially preferred is the use of lecithin from hen eggs and/or from soy. A further source is, for example, rape.

The lecithin from soy is obtained by extraction of soy with ethanol and then the lecithin is purified by chromatography and hydrated. The as-obtained phosphatidyl-choline (lecithin) contains as fatty acid moieties 80-90% by weight stearic acid, preferred about 85% by weight stearic acid and 10-20% by weight palmitic acid, preferred about 15% by weight palmitic acid. An especially suitable lecithin is Phospholipon® 80H as well as Phospholipon® 90H obtainable from PHOSPHOLIPID GmbH, Köln, Germany.

Lecithin has manifold uses in cosmetic formulations. As a component of ointments and creams it enhances the permeation of active agents into the skin and clearly improves the water retaining capability of the stratum corneum in gel formulations. Due to the increase of the skin's moisture uptake the roughness of the skin is decreased. Lecithin features as emulsifier a very low irritation potential (no washout effect). With lecithin w/o-emulsions with high water content can be prepared. Lecithin is a natural antioxidant and is used in bathing oils as emulsifier. Hydrated lecithin is suitable as a gelling and thickening agent in cosmetic formulations.

A further substantial component of the formulations according to invention are essential fatty acids, which are added to the formulation preferably in the form of suitable oils. Such suitable oils are for example sunflower oil, olive oil, corn oil, linseed oil, cod-liver oil and fish oil.

These oils of preferably native origin are added to the formulations according to invention in an amount of 3.0-20.0% by weight, preferred 6.0-16.0% by weight, further preferred 7-14% by weight, further preferred 8.0-12.0% by weight, further preferred 9-11% by weight and especially preferred 10.0% by weight.

These oils of native origin are selected according to their content as well as their composition of fatty acids, including essential fatty acids, their technological suitability and in dermatological regard. The single dermatologically active components as well as their composition are sufficiently described in the relevant technical literature. The refined sunflower oil in pharm. EUR. quality is preferred for the formulations according to invention. This refined sunflower oil (Helianthi annui oleum raffinatum) is obtained from the seed of Helianthus annuus C., has a relative density of 0.921 and a refractive index of 1.474, an maximum acid value of 0.5 (determined with 10 g of substance), a maximum peroxide value of 10, as well as the following fatty acids composition: palmitic acid 4-9% by weight, stearic acid 1-7% by weight, oleic acid 14-40% by weight and linoleic acid 48-74% by weight. A further especially suitable sunflower oil (Helianthus annuus L.) consists of 39% by weight oleic acid, 34% by weight α-linoleic acid, 13% by weight β-linoleic acid, about 4% by weight glycerol, about 9% by weight saturated fatty acids (palmitic, stearic, arachidic and linocerinic acid), carotinoids, as well as lecithin. The fatty acid fraction of the used sunflower oils contains preferably 15-35% by weight oleic acid, 50-72% by weight linoleic acid. Inter alia oleic acid is also referred to as acidum oleinicum, cis-9-octadecenoic acid, elainic acid or oleinic acid.

Essential fatty acids (EFA) are fatty acids, which can not be produced by the human body itself and hence have to be incorporated with nutrition.

Essential fatty acids always exist in the cis- and not the trans-configuration and are characterized by two or more unsaturated carbon atoms, i.e. by at least one double bond. Where the first double bond is positioned in the fatty acid chain, viewed from the methyl-end (omega-end), is characteristic. There are two types of essential fatty acids, the omega-6, derived from the cis-linolenic acid, and the omega-3, derived from the α-linolenic acid. The most important groups of omega-fatty acids are the omega-3-, -6- and -9-fatty acids.

The omega-3-fatty acids include α-linolenic acid, eicosapentaenoic acid and docosahexaenoic acid.

The omega-6-fatty acids include γ-linolenic acid, linoleic acid, arachidonic acid, delta-13-cis, 16-cis-docosadienoic acid (22:2), delta-11-cis, 14-cis-eicosa-/icosadienoic acid (20:2) and delta-7-cis, 10-cis-hexadecadienoic acid (16:2).

The omega-9-fatty acids include oleic acid (delta-9-octadecenoic acid; 18:1), gondonic acid (delta-11-cis-eicosen-/icosenoic acid; 20:1), erucic acid (delta-13-cis-docosenoic acid; 22:1) as well as nervonic acid (delta-15-cis-tetracosenoic acid; 24:1).

The highest content of linoleic acid is found in vegetable oils, such as for example safflower oil or thistle oil, sunflower oil, hemp and soy oil, and in vegetable margarine.

The triple unsaturated α-linolenic acid (9,12,15-octadecatrienoic acid) is most notably found in linseed oil (55%), walnut oil (14%), rape oil (11%) and hemp oil (7%).

The following table 1 shows important omega-3- and -6-fatty acids, their chain length and position of the double bond as well as their sources.

The cosmetic and/or dermatological formulations according to the invention contain further glycerin as 85%-solution in water, propylene glycol respectively polyethylene glycol as consistency agent, benzyl alcohol, benzyl acetone and/or benzaldehyde as well as phenylethyl alcohol and/or 2-phenylacetate. The glycerin used can have a water content of up to 20%. Instead of glycerin a combination with glycerin ethylene glycol, 1,3-propanediol, tert-butylalcohol and/or alcohols with boiling points above 125° C., preferred above 150° C. and preferred diols or triols can be used.

Benzyl alcohol, benzyl acetone and/or benzaldehyde are added as a permeability conditioners for accelerating the metabolism processes in the skin as well as a stabilizing agents for the formulation.

Phenylethyl alcohol and 2-phenylacetate serve also as permeability conditioners for accelerating the metabolism processes in the skin and also stabilize the formulation.

Especially benzyl alcohol as well as phenylethyl alcohol lead additionally to an unexpected synergistic effect between the components of the cosmetic and/or dermatological formulation according to invention, the consequence of which is, that in the case of a very good moisture supply of the skin the metabolism processes in the skin are stimulated and accelerated and additionally a supporting of the lipid barrier takes place. Thereby, the formulations according to invention are suitable for both the treatment of damaged skin and the smoothing of crinkles in the case of longer application. Thus, formulations are provided, which are not only suitable for the dermatological application in case of for example acne, neurodermatitis and/or dermatitis but achieve simultaneously also a cosmetic effect, such as the smoothing of crinkles, by supporting the buildup as well as the regeneration of the lipid barrier and/or the stimulation as well as acceleration of the metabolism processes in the skin. Especially advantageous is the addition of benzyl alcohol and/or phenylethyl alcohol, which also contribute to a clearly increase in viscosity besides a distinct synergistic effect. This significant spontaneous increase in viscosity, especially achieved by benzyl alcohol, is substantial for the formation of the matrix or gel framework and hence for the dermatological/cosmetic function of the formulations according to invention. These two components and especially the benzyl alcohol seem to play an important role in the formation of the framework in the formulation. By the addition of these components the moisture supply of the skin is clearly increased. Another important component of the formulation is propylene glycol, which is preferably utilized in percentage amounts by weight of at least 8% by weight, further preferred 9% by weight, 10% by weight, 11% by weight, 12% by weight, 13% by weight, and especially preferred 14% by weight. The function of propylene glycol in the formation of the special framework of the formulations according to invention is not clarified yet, but an effect on the consistency of the formulation can be clearly verified.

Ethylene glycol, 1,3-propanediol, tert-butylalcohol or other diols or triols or alcohols with boiling points above 125° C. and 150° C., respectively, are added instead of glycerin or together with glycerin in amounts, so that the afore-mentioned ranges are not exceeded or undershot.

The amount of utilized propylene glycol and/or polyethylene glycol is 0.5-50.0% by weight, preferred 6-35% by weight, 7-30% by weight, 7.5-28% by weight, 8-26% by weight, 8.5-25% by weight, 9-24% by weight, 9.5-23% by weight, further preferred 10.0-22.0% by weight, further preferred 11-21% by weight, 12-20% by weight, 13-19% by weight, further preferred 14.0-18.0% by weight, further preferred 15-17% by weight and especially preferred 16.0% by weight. Additionally it is preferred, if the afore-mentioned percentage amounts by weight represent only propylene glycol, i.e. polyethylene glycol is not present. Hence, advantageous are only small amounts of polyethylene glycol up to a maximum of 30% of the percentage amount by weight of propylene glycol, preferred up to a maximum of 20%, further preferred up to a maximum of 20%, further preferred up to a maximum of 15% and especially preferred up to a maximum of 10% of the percentage amount by weight of propylene glycol.

Benzyl alcohol, benzyl acetone and/or benzaldehyde are used in an amount of 0.1-15.0% by weight, preferred 1.0-5.0% by weight, further preferred 2.0-4.0% by weight and especially preferred 3.0% by weight.

The cosmetic and/or dermatological formulations according to invention contain phenylethyl alcohol and/or 2-phenylacetata in an amount of 0.1-15.0% by weight, preferred 0.2-5.0% by weight, further preferred 0.3-1.5% by weight and especially preferred 0.5% by weight.

The afore-mentioned components are admixed with purified water in an amount, such that the formulation is complemented to 100% by weight.

Especially preferred is a formulation of the following components: lecithin, native oil with a defined content of essential fatty acids, such as sun flower oil as well as glycerin, propylene glycol, benzyl alcohol, phenylethyl alcohol and purified water.

The compositions according to invention can be still further admixed with usual odor agents resp. perfumes, dyes, preserving agents, viscosity increasing agents and/or UV-filters. These additives serve especially for increasing the color, light and/or perfume stability of the formulations and the shelf life or imparting consistency, respectively. Suchlike additives are in total present in the formulation by not more than 10% by weight, preferred 8% by weight, further preferred 6% by weight and especially preferred 4% by weight.

The cosmetic and/or dermatological formulations according to invention can be used advantageously for the treatment of all of the forms of impure up to damaged skin. Impure up to damaged skin means for example all of the forms of acne, neurodermatitis or atypical dermatitis.

Cosmetic and/or dermatological formulations mean especially skin creams, skin lotions, milks, ointments, oils as well as balms and all of the other formulations suitable for topical application.
